From 9f5071010347b2134e1139dca2396a0cea8130dc Mon Sep 17 00:00:00 2001 From: Lijun Ou Date: Sat, 8 Dec 2018 18:40:07 +0800 Subject: RDMA/hns: Init qp context when modify qp from reset to init It needs to clear qp context previous when init qp context. Otherwise, the newly created qp context residue has the contents of the qp context before the uninstall, and the qp context content is disordered, causing the task to fail.
